Notes:
Scientists at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru develop a new method to improve water-splitting catalysts for clean hydrogen production. The key problem addressed is the slow Oxygen Evolution Reaction (OER) compared to the Hydrogen Evolution Reaction (HER). They work on Coordination Polymers (COPs), made of metal ions and organic molecules, used in electrolysis. Coordination Polymers (COPs) normally show low activity because water blocks their active reaction sites. The team applies argon plasma treatment to create coordinatively unsaturated metal sites. This sharply improves the electrocatalytic performance without damaging structure.

Notes:
World Soil Day is observed annually on 5 December to highlight the importance of healthy soil for food security, ecosystems, and human well-being. The theme for World Soil Day 2025 is “Healthy Soils for Healthy Cities”, focusing on the role of urban soils. Urban soils face pressures from rapid urbanisation, soil sealing, pollution, and loss of organic matter. Healthy soils in cities support food production, water purification, carbon storage, temperature regulation, and biodiversity conservation. Preserving soil health is essential for climate resilience, urban planning, and sustainable development.
